Development of Carbon‐11 Labeled Pyrimidine Derivatives as Novel Positron Emission Tomography (PET) Agents Enabling Brain Sigma‐1 Receptor Imaging

Advanced Science, EarlyView.
Novel carbon‐11 labeled pyrimidine derivatives are developed as PET imaging probes for visualizing sigma‐1 receptors in the brain. [11C]CNY‐01 demonstrates superior brain uptake and binding specificity in both rodents and non‐human primates. The study reveals decreased sigma‐1 receptor expression in Alzheimer's disease, offering a promising tool for ...

Degradation of Glyphosate to Benign N‐Formyl Glycine Using MOF‐808 Nanocrystals

Angewandte Chemie, EarlyView.
A Zr‐based metal–organic framework (MOF‐808) with different crystal sizes and designed defect sites was employed as an efficient heterogeneous catalyst for the complete degradation of glyphosate at room temperature. The degradation mechanism produces N‐formyl glycine and hydroxymethyl‐phosphonate. Abstract Glyphosate (N‐phosphonomethyl glycine, GPh) is

Scintillation characteristics of the EJ-299-02H scintillator

Review of Scientific Instruments
A study of the dead layer thickness and quenching factor of a plastic scintillator for use in ultracold neutron (UCN) experiments is described. Alpha spectroscopy was used to determine the thickness of a thin surface dead layer to be 630 ± 110 nm.

Synchrotron Radiation‐Based Tomography of an Entire Mouse Brain with Sub‐Micron Voxels: Augmenting Interactive Brain Atlases with Terabyte Data

Advanced Science, EarlyView.
Extended‐field acquisition enables sub‐micron X‐ray imaging of a full mouse brain. The 3.3‐teravoxel volume is reconstructed, registered to a reference atlas, and stored in hierarchical format to augment currently available atlases and improve resolution in the third dimension by an order of magnitude.

X‐ray microscopy and automatic detection of defects in through silicon vias in three‐dimensional integrated circuits

Engineering Reports, Volume 4, Issue 12, December 2022., 2022
Through silicon vias are a key enabling technology for interconnection and realization of complex three‐dimensional integrated circuit components. A combined x‐ray microscopy and deep learning object detection workflow for automatic micrometer accurate defect location on liner‐TSVs was developed in this work by developing proper scan recipes and a ...

Soft, environmentally degradable microfluidic devices for measurement of sweat rate and total sweat loss and for colorimetric analysis of sweat biomarkers

EcoMat, Volume 5, Issue 1, January 2023., 2023
Soft, skin‐interfaced microfluidic systems exploit biodegradable thermoplastic copolyester elastomers for the microfluidic layers, cellulose films and pressure sensitive adhesives as sealing layers, and carefully selected chemical reagents as colorimetric assays for monitoring sweat loss, sweat rate, pH, and chloride concentration.

High Resistivity of Single Crystal CsPbBr3 Semiconductor for Radiation Detection via Proposed Temperature‐Concentration Balance Method

Advanced Electronic Materials, EarlyView.
This study introduces a temperature‐concentration balance (TCB) method to grow high‐quality CsPbBr₃ single crystal with improved phase purity and structural stability. The crystals exhibits a sharp emission peak at 527 nm, narrow full width at half maximum (21.1 nm), and high resistivity (up to 3.97 × 10¹⁰ Ω·cm).
